FILTER.

To all whom 'it may concern:

.Be it known that I, FERDINAND TUREK, citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Filters, of which thefollowing is a specification.

This invention relates to filters and has for its object to provide animproved filter construction.

In the accompanying drawings, Figure 1 is a vertical cross section ofone of the filters; Fig. 2 is a perspective of one of the filteringelements of Fig. l; Fig. 3 is a section on line 4-4g and Fig. 4 is asection on line o o.

The casing of the filter is shown at 1 and stands on legs, 2 and isprovided with a cover 12 which is held to the casing by means of a screw14 with an upper handle for turning same. Screw 14 is mounted upon anarched arm 11 pivoted to the casing 1 at 9 and provided with means at 10to secure same to the other side of the casing.

The lter is provided with a central outlet pipe 5 at the bottom, andwith an inlet pipe 6 offset from the center of the lter. Said pipe 5 isprovided with a valve 4 and with a branch pipe 24 having a valve 3, thebranch 24 being inside of valve 4. Valve 3 is normally closed. Branch 24is connected to a water supply (not shown) for the purpose to behereinafter described.

The filter consists of a plurality of trays or receptacles 1G havingtheir sides perforated, and filled with filter mass so arranged that thebeer is forced through the filter mass into the outlet pipe 5 and thusfiltering the beer or other beverage forced therethrough. Thereceptacles are rectangular as shown in Fig. 2, and have centralopenings 17 and also solid corners 26. They also have rings 18 securedin the central openings, and these rings connect upstanding cylindricalsieves or perforated cylinders 19. These receptacles rest one upon theother and can be assembled in any number, the ring 1S of the upperreceptacle 16 setting on the cylindrical sieve 19 below. The trays orreceptacles are alternately inverted and placed one above the other, thesleeves 18 projecting through the central openings to rest on the sieves19. The upper inverted receptacle 16u differs from the receptacle 16, in

that the central opening is closed and has a depending cylindricalportion 18a to rest on Specification of Letters Patent.

the sieve 19 below. Each of these receptacles is filled with filter mass2O and has perforated plates or sieves 22 separating the filter mass ofthe adjacent receptacles for convenience in placing the elements of thefilter together and for removing saine. A spider 15 sets on the upperreceptacle 1Ga and screws 13 which extend through the cover 12 from across piece 11, bear on the spider and serve as means for compressingthe filter mass. The lower receptacle sets on the radially disposed ribs21 which support same above the bottom of the chamber to allow freecirculation of the beer around the base and up the sides of thefiltermass.

A pipe 30 extends up the central recess and has apertures 2S in theplane of screens 22 and an upper cap 29 to close the upper end. The pipe30 has a valve 27, and water or steam may be forced through pipe 30 whenvalve 27 is opened. This is used in connection with the other inlet 24,for cleaning the filter, or may be used alone. The steam and .waterunder pressure are forced out apertures 28 and have a flushing effect,loosening up the filter mass 20 and thoroughly cleansing same. Thereceptacles 16 and 16a are made large enough to extend close to thecasing l, leaving just enough space for beer to pass up.

In operation, beer to be filtered is forced through the pipe 6 into thefilter and Patented sept. 6, 1910..

through the same and out at the pipe 5,'

mass and are entirely separate and inde` pendent. The corners and middleare constructed so that the filter mass in the layers is in thecompressed form desired, and consequently the layers must all work alikeand the filter mass does not have to be greatly compressed, to hold itin place.

In this filter, the filter mass remains held in the sieves, the same asin the press, and the pressure does not compress the filter mass inside.Likewise when the second layer is placed upon the first it cannotcompress the filter' mass in the first layer. Thus the fluid has freepassage in the regular filtration process, and the impurity isdistributed evenly throughout the filter mass. As the layers are not ina greatly compressed form, it is easy to cleanse and rinse the filterwhen the impurity is being removed, which saves taking the filter apart,and prevents part of the loss of time and material incident thereto.

The rings in the middle have the purpose only of compressing the filtermass, so that the fluid may not pass through at that place; theperforated cylinders on the rings preventing the weight of the upperlayers from compressing the filter mass in the lower layers, and in eachcorner. The trays having all sides perforated allows the liquid to flowthrough at all points, and no space is lost in the filters, and theentire mass works uniformly, with a free passage,` the fiuid not losingin quality. In this form of sieves, great pressure is not required, andpower is saved.

In cleaning or washing out the filter, a central perforated pipe isintroduced through which steam is blown into the spaces between thesieves, for purposes of cleaning. The steam coming into contact with thewater is condensed and forms a sort of water hammer effect, which isutilized for getting rid of impurities. The water in the filter mass isnot allowed to exceed a certain number of degrees, so as not todeteriorate the quality of the filter mass,

I claim:

l. A filter comprising a casing having an inlet and an outlet, and aseries of trays containing filter mass superposed in said casing, thetrays having perforated inner and outer side walls, the former forming acentral conduit with perforations throughout the full length thereof anddirectly opposite the filter mass and the latter being spaced slightlyfrom the sides of the casing, whereby liquid may flow through said sidewalls and the filter mass therebetween.

2. A filter comprising a. casing having an inlet and an outlet, and aseries of trays having perforated bottoms and sides and containingfilter mass, placed one above the other in said casing, the trays beingalternately inverted with the bottom of one adjacent the bottom of theother, the outer sides of the trays being spaced'from the sides of thecasing, and a central conduit having perforated sides, extending throughthe trays.

3. A filter comprising a casing having therein a series of filter unitswith central openings forming a conduit through said units, and a pipeextending through the end of the casing and projecting into said conduitand having spray holes in the sides.

4. A filter comprising a casing having therein a series of filter unitswith a central perforated 'tube extending through said units, and aspray pipe extending through the casing wall and into said tube andhaving laterally directed spray holes.

5. A filter comprising a casing, and a pair of units therein eachconsisting of a tray with a perforated bottom and sides and a filling offilter mass, the bottom having a central opening, and a perforated tubeextending through said units and in line with the said openings, thetrays being placed together wit-h their bottoms at opposite ends of thestructure.

6. A filter comprising a casing, and a series of superposed unitstherein comprising 'trays with perforated bottoms and sides and afilling of filter mass, the bottoms of the trays having central alinedopenings, rings in said openings, and tubes of perforated materialextending through the units with perforations beside 'the filling andbetween said rings.

In testimony whereof, I do affix my signa.- ture in presence of twowitnesses.
